Rsync_bpc Error - BackupPC 4

I am using BackupPC 4.0 on a debian distro to backup two windows computers running Cygwin. I am using rsyncd as the vehicle to back them up. When I try to start a backup, the backup fails apparently because of an rsync_bpc issue. The log file entries are below:

In one of the log files, it indicates the following: Running: /usr/local/bin/rsync_bpc and it has the following error message: ERROR: failed to read a password from /data/BackupPC/pc/agm-pc/.rsyncdpw5658.

Does anyone recognize that error and know what it means? It seems as though it needs some sort of password but I don't know where to input a password. The only password I know of is in the secrets file on the target Windows machines, but this looks like it is not even connecting to even get that far.

Hi akibuflash,
I have the same issue on all my machines on my test rig.
The path to the rsyncpw file listed in your log lives in your BackupPC pool directory.

I was curious to see if the file was created at all, so I ran the following command in the dir that supposedly would contain the file:

watch -n 0.1 ls -lh

I could briefly spot that the file is actually created.
Next step was to check the contents of the file, did a similar thing, just ran:

watch -n 0.1 cp .rsyncdpw* rsyncpw.bak

Then checked the contents of the file. Now, I'm not sure if the cp command grabbed the file before anything was actually written to the file, but it appears to be empty.

I added a password to the rsyncd password filed in the global config, and did the same thing again, "watch -n 0.1 cp .rsyncdpw* rsyncpw.bak".
This time the file contained the password specified in the global config.

I ran out of time after that. Let me know if you have any progress and manage to work around it.
Cheers
